This ProMatrix track rotor kit was developed for competition as a direct replacement for the 12.8” diameter front rotors found on all 1997-2004 C5 models, and all 2005-2013 C6 base model Corvettes. GT-48 directional vane Spec37 race alloy rotors are mounted to the OE hubs with lightweight forged aluminum hats to deliver maximum thermal stability, cooling efficiency, and durability in sustained high heat braking cycles. Use these rotors for all types of auto-cross or road course competition where race compound pads are being used in the OE calipers, or with any aftermarket caliper kit made for use with the OE dimension rotors. Wilwood also offers three pad compounds for use in the OE calipers covering all types of vehicles from dual-sport street and track prepped cars, to dedicated race-only applications. Brake pads must be ordered separately.
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 250 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
